The suspects from Joplin, Missouri, are considered armed and dangerous and should not be approached, authorites warned.

Harper's Facebook page contains this post from Jan. 24, next a photo of her and Fitzgerald:

"Hated by manyWanted by plentyDisliked by someConfronted by none."

Fitzgerald is accused of entering a home early Sunday through a garage door Sunday and ordering the homeowners to turn over the keys to their Ford Edge. He forced the wife into her car at gunpoint as Harper joined him, police said.

The homeowners were not identified.

Fitzgerald and Harper took the woman to a hospital about nine miles away and ordered her out of the car, authorities said. She was not harmed, police said, according to NBC News.

The couple also is wanted for the abduction of a motel manager earlier Sunday, police said. The male clerk was shoved into the back of his car and driven to a McDonald's parking lot, where Fitzgerald and Harper tried to rob a female employee at gunpoint, officials said.

The woman ran, and the pair drove to Vestavia Hills, where they deposited the motel clerk, and then allegedly abducted the homeowner.
